Molecular epidemiology and phylogenetic analysis of bovine picobirnaviruses causing calf diarrhea, in Iran.

Picobirnavirus (PBV) is an enteropathogen virus causing diarrhea as an opportunistic virus in its vertebrate host. There is no information about human or animal PBVs in Iran. The aim of the present study was the investigation of the epidemiology of bovine PBV in the broad geographical area of Iran.

In vivo evaluation of toxicity and antiviral activity of polyrhodanine nanoparticles by using the chicken embryo model.

Evaluation of the potential cytotoxicity of polyrhodanine nanoparticles is an important factor for its biological applications. In current study, for the first time histopathological and biochemical analysis of polyrhodanine besides of its antiviral activity against Newcastle disease virus (NDV) were examined on chicken embryo model. Polyrhodanine was synthesized by the chemical oxidative polymerization method.

The Effect of Stevia on the Chicken Embryo Heart.

Background: Stevioside is one of the most important food additives that has become well known for its sweetness. The aim of this study was to evaluate the impact of Stevioside on the heart.

Methods: 4-day-old embryonated chickens eggs were inoculated with Stevioside and kept until hatching.

Genotyping and determining the distribution of prevalent G and P types of group A bovine rotaviruses between 2010 and 2012 in Iran.

Determination and distribution of the G and P genotypes of group A bovine rotavirus was investigated on 386 fecal samples collected from calves with diarrhea using a semi-nested RT-PCR typing assay. Samples were collected from 11 provinces of Iran during 2010-2012. The provinces divided into 5 different groups based on geographical distance and climates.
